Order FSH Blood TestFollicle-stimulating hormone (FSH) is a glycoprotein hormone produced by the anterior pituitary gland. It belongs to the gonadotropin family, alongside luteinizing hormone (LH), and acts on the gonads to regulate reproductive function. An FSH blood test measures the concentration of this hormone in serum, providing a direct view of pituitary signaling and, by extension, the status of the hypothalamic-pituitary-gonadal axis.
About FSH Blood Test in Bothell
FSH testing is used to evaluate reproductive and pituitary function in both males and females.
In females, FSH drives the recruitment and maturation of ovarian follicles and stimulates estradiol production. Its levels fluctuate across the menstrual cycle, rising in the early follicular phase and peaking just before ovulation. Persistent elevation can indicate diminished ovarian reserve or primary ovarian insufficiency, while low levels may point to hypothalamic or pituitary dysfunction.
In males, FSH acts on Sertoli cells within the seminiferous tubules to support spermatogenesis. Elevated concentrations are often associated with impaired testicular function, whereas low values may reflect inadequate pituitary stimulation. Because FSH works in concert with LH and testosterone, it is rarely interpreted in isolation.
The test requires a simple blood draw, typically from a vein in the arm. Results are reported in milli-international units per milliliter (mIU/mL). Reference ranges vary by sex, age, and menstrual cycle phase, so values are best interpreted by a clinician alongside the patient's history, symptoms, and other hormone measurements such as LH, estradiol, or testosterone.
